APPARATUS FOR MEASURING RADIATION DIRECTIVITY OF ANTENNA

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for measuring the radiation directivity of an antenna in which the antenna to be measured does not influence the radiated electromagnetic field even when the antenna is brought close to a super-vicinity area to the antenna to be measured. SOLUTION: In the apparatus for measuring the radiation directivity of an antenna to be measured which measures the two-dimensional electric field distribution or the interference complex data distribution as the two-dimensional magnetic distribution formed by the antenna to be measured to measure the radiation directivity of the antenna to be measured by the relative surface- scanning of the antenna to be measure and a probe antenna, the probe antenna is formed of a shielded loop antenna, and the radiation directivity can be measured without deforming the electromagnetic field to be measured.
